The correct answer is:
| A | B | C |
| DNA | Linker histone | Histone octamer |
Histone octamer : It is made up of 8 molecules of histone proteins. Histone proteins are positively charged basic proteins. These proteins are rich in basic amino acids like lysines and arginines. Both of these amino acids possess positive charges in their side chains.
Nucleosome : DNA (negatively charged) wraps the positively charged histone octamer. In a nucleosome, about 200 bp are present in DNA.
